4 Claims. (CL 20- 42) This invention relates in general to improvements in Window construction, and more particularly to an improved hinge construction for pivotally mounting sash.

The primary object of this invention is to provide an improved hinge construction which permits the pivotal mounting of sash in a frame Without necessitating special fittings carried by the frame for receiving hinge pins and the like.

Another object of this invention is to provide a hinge member readily secura'ble to a sash and being so shaped whereby a hinge pin thereof may be directly journalled in a frame member of a frame in which the sash is mounted.

Still another object of this invention is toprovide a sash construction having a pair of hinge members and a pair of operator brackets, the hinge members and the operator brackets being secured in place upon the sash by the same fasteners.

Yet another object of this invention is to provide a hinge member for a sash which is so constructed whereby the hinge member reinforces a stile member of the sash to which it is attached.

A further object of this invention is to provide a hinge member which is so configurated that it may be readily concealed between a sash stile and a frame jamb.

With the foregoing and other objects in view, which will become more apparent as the nature of the invention is better understood, the same consists of a sash hinge construction embodying novel features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings and defined in the appended claims.

In the drawings:

Figure 1 is a fragmentary vertical sectional view through an awning type window and shows the mounting of sash therein; intermediate portions being omitted;

Figure 2 is a fragmentary horizontal sectional view taken along the section line 2--2 of Figure 1;

Figure 3 is a fragmentary vertical sectional view taken along the section line 33 of Figure 1; and,

Figure 4 is a fragmentary exploded perspective view of a sash of the window of Figure 1, the glazing and intermediate portions being omitted.

Referring now to the drawings in detail, it will be seen that there is illustrated an upper portion of an awning type window it) which includes a frame 12 and a plurality of vertically arranged and horizontally disposed sash members 14.

Illustrated in Figure 4 is one of the sash 14 which, for the purpose of describing the present invention, may be considered an example of all of the sash of the window 10. The sash 14 is formed of a pair of stiles 16 connected together by rails 18 and 20. Inasmuch as only the stiles 16 play an important part in the present invention, only they will be described in detail. Each stile 16 includes an interior flange 22 and an exterior flange .24 connected by a web 26 secured to intermediate portions thereof.

In order that the sash 14 may be mounted in the frame 12 'for pivotal movement there are provided a pair of hinge members 28, one for each stile 16. Each hinge member 28 includes an elongated lower portion 30 and an outwardly offset upper portion 32. The upper portion 32 is provided with an outwardly directed hinge pin 34.

The lower portion 30 has projecting from the inner face thereof adjacent its connection to the upper portion 32 an aligning pin 36. Below the pin 36 the lower portion 30 is provided with a pair of apertures 38. The upper part of the web 26 is provided with an upper aperture 40 in which the pin 36 is seated. The web 26 is also formed with apertures 42 aligned with the apertures 38. The lower portion '36 is secured in face-to-faceengagement with the outer face of the web 26 by fasteners 44 passing through the apertures 38 and 42.

Each stile 16 is also provided with an operator bracket 46. The operator bracket is triangular in outline and includes an exterior vertical side 48 and upwardly converging sides 50 and 52. The operator bracket 46 includes a pair of vertically spaced ears 54 secured along the side 48. The ears 54 are offset from the main portion of the operator bracket 46.

Formed in the flange 22 in alignment with the apertures 42 are vertically elongated slots 55 through which the cars 54 pass. The ears 54 have internally threaded apertures 56 therein aligned with the apertures 42. The fasteners 44 are engaged in the apertures 56 and clamp the ears 54 and the hinge member 28 to opposite faces of the web 26. It is to be noted that the hinge member 28 reinforces the Web 26 and is disposed within the general confines of the stile 16 and that the side 48 abuts the flange 22.

The frame 12 is formed of a pair of jambs 58 connected by a header 6t} and a sill (not shown). Inasmuch as only the jambs 58 form a part of this invention, only they will be set forth in detail. Each of the jambs 58 includes an interior flange 62 and an exterior flange 64 connected by an interior web 66. An exterior web 68 is connected to the flange 64.

The web 68 of each jamb 58 is relatively heavy and has seated therein a bushing 70 for each vent 14. Tournaled within each bushing '70 is a hinge pin 34 to pivotally mount the vents 14 in the frame 12 without requiring extra brackets. It is to be understood that the pins 34 are inserted into the bushings 70 before the hinge members 23 are secured to the stiles 16.

The flange 24 and web 26 of each stile 16 together with the flange 64 and web 63 of the associated jamb 58 forms a vertical space 72. Inasmuch as the hinge members 28 are die cast or formed of bar stock and since they are within the confines of their stiles 16, it will be readily apparent that the hinge members may be concealed within their respective spaces 72, when the sash 14 are in closed positions.

In order that the sash 14 may be simultaneously opened and closed, there is concealed in each jamb 58 a vertically extending actuator bar 74. The bar 74 is connected to the operator brackets 46 by pins 76 carried by the operator brackets 46 at upper corners thereof. The pins 76 pass through the bar 74 and are retained in place by locking rings 78. When the bars 74 are pulled down- Having described the invention, what is claimed as new is:
